Stephen Kern, a professor of history at The Ohio State University, wrote the chapter “Wireless World” about the famous sinking of Titanic. Kern writes about how the wireless technology used by the boat was essential for communication and the safety of its passengers. The Titanic, Known for being one of the newest and largest ships at the time, headed high speed through the North Atlantic waters. At 11:40 P.M. an ice berg was spotted and as the ship made a rapid turn, it skimmed the ice causing a three hundred foot gash. After realizing the severity of the problem, a wireless operator sent out a distress signal and soon enough ships all around were notified of the possible sinking. Ten ships heard the call but were too far to respond in time. One ship close enough, the …show more content…
“enabled the peoples of many lands to stand together in sympathetic union, to share a common grief” (William Alden Smith). In the days after the event Kern states that people were praising the communication that made it possible to save the lives they did. The history of this technology begins with a theory by James Clerk Maxwell in 1864, who said that electromagnetic waves should have the ability to be propagated through space. This theory came to life when Heinrich Hertz created those waves and seven years later Guglielmo Marconi created a device that could transmit and receive them. Kern states that Later on Marconi went to England where he established the first coast station on the Isle of Wight so that it was possible to communicate with ships at sea. This type of transmission became so popular that in 1904 Marconi’s company created the first news service. This type of wireless communication got a lot of attention when a message was transmitted that allowed for the arrest of a man who murdered and buried his wife. The technology did end up saving lives at sea, in 1909, 1,700 lives were saved just because of a wireless call. Along side all the
In 1906, a scientist by the name of Richard Dixon Oldham had suggested a theory structured another scientists findings by the name of Emil Wiechert. Oldham had identified that S waves and P waves behaved differently and
The urgency of communication was never much felt until the beginning and use of telegraphy. It was much easier to transmit and receive messages over long distances that no longer needed physical transport of letters.
Whether fortunately or unfortunately, the limits of innovation are often put to the test. In the case of a submarine launched to sea in 1938, the USS Squalus, bad luck proved disastrous. Within minutes of a test dive, twenty-six men drowned. Years later, Peter Maas compiled the known information about the tragedy into The Terrible Hours: The Greatest Submarine Rescue in History. Over the heartbreaking journey of hopelessness to hope, crisis to survival, and depths to ascension, Maas weaves the sad tale depicting the unknown dangers that technology possesses.
Electromagnetic waves are waves that can propagate even though there is no medium. A magnetic field that changes with time can generate an electric field that also changes with time, and an electric field that changes with time can also produce a magnetic field. If the process is continuous it will produce a magnetic field and electric field continuously. If these magnetic fields and electric fields simultaneously propagate (spread) in space in all directions then this is a symptom of the wave. Such a wave is called an electromagnetic wave because it consists of an electric field and a magnetic field that travels in space.
Imagine that the person you love most in the world dies. How would you cope with the loss? Death and grieving is an agonizing and inevitable part of life. No one is immune from death’s insidious and frigid grip. Individuals vary in their emotional reactions to loss. There is no right or wrong way to grieve (Huffman, 2012, p.183), it is a melancholy ordeal, but a necessary one (Johnson, 2007). In the following: the five stages of grief, the symptoms of grief, coping with grief, and unusual customs of mourning with particular emphasis on mourning at its most extravagant, during the Victorian era, will all be discussed in this essay (Smith, 2014).
“Yeah, we hit a huge berg and we’re taking on water fast down below.” He replied. Before I had time to think, the lifeboat was lowered into the water slowly. I felt sorry for the people on that lower deck because the ship was only half full of us rich first-class folk. The same guard had hopped onto the ship to lead it away from the dying giant. After seeing the Titanic from a distance, I could see that its long rows of deck lights weren’t perpendicular to the ocean anymore, but slanted way up.

These are troubling times; People are out of work, there are earthquakes happening all around the world, strange weather patterns. As a result, it seems like every day a new country is breaking out in riots. A people’s ability to rise above the animals and organize as a civilization requires effective communications. Sure, ours is a society with many modern conveniences; Cell phones and the Internet are in the palms of our hands. But what happens when the networks of communication that those people have come to rely on get overloaded or destroyed? When the world is in turmoil, only Amateur Radio provides light, provides support and hope. The licenced operators of these radios, called “Hams,” are constantly training for these moments.
Providing the basis of nineteenth century physics, Young's Double Slit Experiment proved that light was made up of waves. During Thomas Young’s time, it was very difficult to describe the behavior of light. The predominant theory was that light was made up of particles. However, in his experiment, Young was able to observe the interaction of light waves when passed through two slits, showing the wave-like nature of light. This report will cover the reasons for Young’s experiment, the experiment itself, and its implications.
On April 12,1914 just before 2 pm, the Captain and crew that helped control the ship, received three ice warnings. The Captain ignored them. At 5:03 pm the got another warning from ocean Liner America, it went unacknowledged.
Time-varying electric fields can bring magnetic fields and vice-versa. Since both fields generate each other, they occur jointly and therefore, propagate as electromagnetic waves.
People started to see the significance of the telephone and what it can accomplish. Now with the help of the telephone, individuals communicated in a much quicker fashion. Once this became evident, it greatly enhanced the use of the telephone. After further development of the telephone, society recognized its ability to allow one to contact another person at any time any place with confidence that the call would be completed. The less time it took to communicate was a big draw for society because messages could be sent instantly. This invention allowed for such...
For instance, throughout the nineteenth century, it was correctly believed that light was a wave. If light were a wave like all other waves, it must have a medium through which to propagate through. This medium was called the ether, a substance which was everywhere throughout the universe. If this hypothesis were true one would be able to calculate the velocity of the Earth through the ether. Many experiments were conducted to determine this velocity the most famous one being the Michelson-Morley experiment.

Throughout this report we have discuessed how Thomas Young proved that light has a wave-like motion. We have also discusses how the double slit experiment proved that light was a wave by allowing people to see the pattern made when light traveled through two slits. We also briefly discussed how elementary particles are thought to act as both waves and particles.
